What should I do today about the overdue notice?

Call the number on your water department notice or request a referral through CHS Backflow at (843) 286-4721. Ask for a pro who can schedule a test as soon as possible. Keep your notice handy so the tester has your account details.

What should I check when hiring a backflow tester?

South Carolina requires all backflow testing to be done by a state-certified backflow prevention tester. Ask the pro for proof of licence and insurance before booking. Certifications expire every three years, so confirm the tester's current status with the South Carolina DES certification list.

How much should a residential backflow test cost in West Ashley?

Published Charleston-area residential annual tests are listed at $45 per location and $55 with test results submitted to the utility. A same-day emergency residential test is advertised at $225. Commercial tests are about $125. Compare the quote for flat-rate pricing and confirm what is included.

What happens if the device fails?

If the test shows a failed device, a repair or rebuild kit typically costs $150 to $400. South Carolina law requires repairs to a backflow prevention assembly to be made by a DHEC-certified backflow prevention assembly tester. Ask the pro to explain the failure and quote the repair before work begins.

What to do next

  1. Find the test type printed on your notice and confirm the device is a Double Check Valve, Reduced Pressure Zone or Pressure Vacuum Breaker.
  2. Verify the tester holds a current South Carolina certification on the DES certification list before booking.
  3. Ask the quote for a flat-rate residential test price and whether test results are submitted to the water department.
  4. Ask the pro for proof of licence and insurance, and ask for the repair cost in writing if the device fails.
  5. Call (843) 286-4721 or email [email protected] for a free quote from a licensed, insured local backflow tester.
